Hello,

I have Hilscher netPI Industrial grade raspberry pi module, I have installed node-red V1.2.2. I tried to run bluetooth node and tried to scan BLE devices, device get detected but after deploying Node red flow I am getting error as "missing" below the bluetooth node and in debug window it gives error "Error: Missing Bluetooth Object, Path:/org/bluez/hci0, Valid Paths:/org/bluez}". please find below screenshot.

Thanks in advance.

Did you follow "[Installation Note (Linux)](https://flows.nodered.org/node/node-red-contrib-generic-ble#installation-note-linux)" in the read me?

Failing that, you could [raise an issue](https://github.com/CANDY-LINE/node-red-contrib-generic-ble/issues).

Hi,
